FAN FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed May 3, 1916. Serial No. 95,147.

To all 'wlwm z't may concern:

Be it known that we, RANDOLPH MvERs and JosEP GRADY FAULKI-NBERRY, citizens of the United 'States, residing at Ardmore, in the county-0f Lincoln, State of Tennessee, have invented a new and useful Fan for Sewing-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it anpertains to make and use the same.

This invention relates to the art of fans and the like, and more especially to an improved fan adapted for use in connection with sewing machines for keeping the operator or seamstress cool. I I

One of the objects of th invention is to provide a fan apparatus for a sewing machine comprising an improved mechanism having connections with a pulley on the .sewing machine to impart motion to the fan, in combination with means upon one of the shafts of the mechanism for holding the'mechanism out of operation.

Another object of the invention is to.

provide a-spherical cage inclosing the fan, thereby protecting the fingers of the operator against injur Another object of the invention is to provide a semi-spherical shield and deflector adapted to be adjusted, to direct theair or the breeze generated by the fan in difle'rent directions, suitable to the operator or seamstress. I

In practical fields the details of construction may necessitate alterations, falling within the, scope of what is claimed.

The invention comprises further features and combinations of parts, as hereinafter ,set forth, claimed.

Referring more especially to the drawings, 1 designates a suitable casing having a top or closure 2 which is secured in place disclosing the devided with a lateral extension casing 4. Mounted in suitable bearings 5 and 6 of the lateral extension casing and the casing 1 is a shaft 6 having a bevel gear 7 at one end and a pinion 8 adjacent the other end.

Also mounted on the shaft 6 is a suitable fly wheel 9. The shaft 6 extends through an additional bearing 10 of a standard 11, rising from the bottom of the casing -1. The bearmgs 5 project from one side of the lateral extension casing 4, and secured upon the shaft 6 by means of suitable pins 12 are collars 13 which are arranged intermediate has a suitable bevel gear 20, meshing with the bevel gear 7, and upon the upper extremity of the shaft 18 a suitable fan 21 is secured by .means of a pin 22, so as to'rotate with the shaft.- The upper end of the casing 16 is by means of screws 3. The casing 1 is proclosed, however, this closed end is provided with an opening 23 for the shaft .18. Fitting the upper closed end/of the extension casing 16 is a sleeve cap 24, to which a downwardly extending flange 25 of a spherical protecting cage 26 is soldered at 2 It is to be noted that the upper part of the sleeve cap is reduced, and encircling the reduced portion is an annular band 28, in tegral with which a semi-spherical deflector 29 is constructed and which corresponds to the shape of the spherical cage 26. This deflector is provided with asuitable handle 30, whereby the same may be adjusted todirect the air or breezefrom the fan in any suitable direction; When adjusting the deflector 29, the circular. band 28 moves u on the reduced portion of the sleeve cap.

ounted in a suitable bearing 31 of the casing 1 and in a bearing 32 of the standard 33, which, in turn, imparts motion to the j which is slidable in its bearings in'the direction of the arrow 41.. A tubular holder 43 and 11 is a shaft 33 which is provided with a gear 34 and a grooved pulley 35. A suitable belt 36 engages the pulley and the pulley 37 of the shaft 38 of the sewing machine 39. It is to b observed that when the machine is operated in the usual mannei', motion is imparted to the belt 36, which transmits power to the pulley-35 and shaft shaft 6 through the medium of the gear 34 pinion 8, and'by virtue of the intermeshlng bevel pinions 7 and 20 motion is imparted to the fan shaft 18. Acollar 39 is secured upon the shaft 33 by means of pins 40, said collar being designed to contact with th side of the bearing 32 of the standard 11, to prevent axial movement of the shaft 33 in the direction of the fly wheel 9. A. wheel 41 having an outer round peripheral edge 42 is mounted upon the shaft 33,

is secured by rivets 44 to the bottom of the casing 1. This tubular holder has a slot 45 in its wall, there being a vertical pin 46 mounted in said holder. The upperv end of the pin 46 is rounded ofi, as shown at 47,

.and between the lower end of the pin 46 and the bottom of the casing 1 a suitable spring 48 is arranged, to hold the pin 46 in a raised position, with the lug 49 in contact with the upper end of the slot 45. The

pin 46 and the holder 43 are so arranged relative to the wheel "41 that the round upper end 47 of the pin is in the path of the outer round peripheral edge of said wheel, as shown in Fig. 2, thereby prevent-' ing' axial movement of the shaft 33 in .the direction of the arrow at. However, by exerting sufficient pull upon the pulley. 35 in the d rection of the arrow a, the round peripheral edge .of the wheel 41 will cam against the round end 47 of the pin 46,

thereby depressing the pin out of the pathof the wheel, and after the wheel 41 has passed the upper end of the pin 46, the

spring 48 will elevate the pin from the other side of the wheel 41, thereby holding the gear 34 out of mesh with the pinion 8, m

which case the belt 36 will operate the .pulley35 idly. A collar 51 upon one end of the shaft 33 contacts with one side of the bearing 32 of the standard 11 and limits the shaft 33 in its axial movement in the direction of the arrow a, with the pin 46 upon the other side of the wheel 41.

The invention having been set forth, what is claimed as new and useful is 1. In combination with a fan driving mechanism, a vertical shaft having a fan upon its upper end, a cage inclosmg the fan, a semi-spherical deflector. corresponding in shape with and fitting the cage and being adjustably mounted for deflecting the air or breeze in different directions.

2. In a device as set forth, the-combina-' tion of a casing having a fail-operating mechanism therein and provided with a vertical extension casing, a shaft driven by said mechanism mounted in said extension caslng and having a fan upon 1ts upper end,

a sleeve capfitted upon the upper end of the extension casing and provided with a spherical cageinclosing said fan, said sleeve cap having a reduced portion, and a spherical carried by the cap, a circular band fitting the reduced portion of the cap and having an integrally connected semi-spherical deflector, the circular band being adjustable whereb the deflector may direct the air or breeze in different directions.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
